New dyno!

Click for large size

3.8 psi, ~20 degrees ignition, tuned till 6000rpm

This was the first run after some tuning on the dyno. Unfortuanately my airbox was leaking after this run...so the last run was only 150hp @ 1.8psi.

Very progressive curve Sebas.... turbo is just starting from the looks of it. I think you lost power under 3000 rpm compared to NA and won power above 3500?

Setup not focussing on lower rpm torque?

Well it's not very good tuned yet in the lower rpm's because the map sensor was not accurate because we had that boostleak. That will be fixed soon I hope :)

very impressive, how much boost can these engines safely take?
1996 EJ9 Civic
1998 BB8 Prelude Motegi VTi
1998, B16A2 EK4 Civic VTi

Aims:
EJ9 - Now my GF's car.
BB8 - Rebuild after crash damage to front end.
EK4 - Daily driver. Strip and track prep once prelude project complete

It think Sebastix is allready on the limit or over it :lol: ;)
Quote from Endyn:"The combustion chamber is a better shape than the DOHC.So don't chunk those 1.6 SOHC engines, they can make really good power. For a pure performance application, regardless of application, I'd choose the SOHC. No bull!"

Running on 4.7psi now!

You should not forget this setup is about 30% more efficient because the ITB's. The stress on the internals is not that big as you think with making almost 200Chp now I think with 4.7psi :) A normal D14 turbo build needs 7-8psi to make around 180-190Chp :) I only need 4-5psi.

I hope my tuner is right...and me too also haha

i've been reading about this and i guess 5-6 psi (0,4 bar) is supposed to be supported by engine internals. More is sayd to be hard for stock engines. Excelent power output... it would be difficult if not impossible to reach these values on NA D14 engine dont you all agree? Cheers
